Transparent windows without the bars/slats, and larger windows

Can we get plain glass without ugly bars ruining the view? Just plain old one-way or two-way glass in a frame.

Also to be able to make larger windows, please include window panes with border/frame on 0, 1, 2, 3, and 4 sides.

Also needed is a way to make windows go around corners. I'd even be happy if you could use silicon (or another new mineral like aluminum) to make solid "clear" forms of all the iron blocks.
